The Problem: A Hidden Short on the Logic Board
Many iPhone 12 Pro users experience a frustrating issue where the touch screen suddenly stops responding, even after a screen replacement. This is often not a screen problem but a fault on the logic board itself, typically caused by a shorted capacitor near the display connector. This simple guide will help you identify and resolve that short.
Step-by-Step Capacitor Solution Guide
This repair requires microsoldering skills and a multimeter to check for the short. Please proceed with extreme caution. The diagram below shows the exact location of the problematic capacitor.
- Open the iPhone: Carefully open the device and disconnect the battery and display connectors. Remove the logic board.
- Locate the Capacitor: Use the provided diagram to find the specific capacitor located near the display connector on the logic board.
- Check for a Short: With your multimeter, check the capacitor for a short to ground. If you detect a short, this is likely the cause of your touch issue.
- Remove the Shorted Capacitor: Carefully remove the capacitor using a heat gun and tweezers. A new capacitor is not always required, as removing the short can be enough to restore functionality.
- Reassemble and Test: Once the capacitor is removed, reassemble the phone and test the touch screen. It should now be fully responsive.
This is a powerful and proven technique for fixing a very specific hardware fault. By addressing the root cause, you save time and money on unnecessary screen replacements.
